UPDATE: MITRE CALDERA 2.3.0

PenTestIT RSS Feed A month ago, MITRE Caldera 2.2.0 was released and a couple of days back now MITRE CALDERA 2.3.0 was released as well. If you remember, I wrote briefly about this automated adversary emulation system in my post titled – List of Adversary Emulation Tools. A lot of changes have be...

The Twists and Turns on the Road to Binee

On August 10, we introduced Binee—a binary emulation environment—to the world at DEFCON and, in an earlier blog, we shared a little bit of how and why we created this tool. Today, Binee is a tool that malware researchers can use as part of their reverse engineering processes. It’s an open-sourced...

Applepie - A Hypervisor For Fuzzing Built With WHVP And Bochs

Binee: Outsmarting Malware with Next-Generation Process Emulation

The Problem with Malware Analysis Threat researchers get thousands of samples of malware every day and, as every researcher knows, it is very difficult to analyze them in a way that allows for intelligent decisions regarding whether a sample’s reputation is good or bad. There are already some qui...

FreeBSD : FreeBSD -- Privilege escalation in cd(4) driver (14a3b376-b30a-11e9-a87f-a4badb2f4699)

To implement one particular ioctl, the Linux emulation code used a special interface present in the cd4 driver which allows it to copy subchannel information directly to a kernel address. This interface was erroneously made accessible to userland, allowing users with read access to a cd4 device t...

Sometime back, an update - the MITRE CALDERA 2.2.0 was released. A lot of changes have been made to create this updated version and as always,...

QEMU: slirp: heap buffer overflow in tcp_emu()

A heap buffer overflow issue was found in the SLiRP networking implementation of the QEMU emulator. It occurs in tcpemu routine while emulating the Identification protocol and copying message data to a socket buffer. A user or process could use this flaw to crash the QEMU process on the host...

QEMU: slirp: information leakage in tcp_emu() due to uninitialized stack variables

tcpemu in slirp/tcpsubr.c aka slirp/src/tcpsubr.c in QEMU 3.0.0 uses uninitialized data in an snprintf call, leading to Information disclosure...

Finding Evil in Windows 10 Compressed Memory, Part Three: Automating Undocumented Structure Extraction

This is the final post in the three-part series: Finding Evil in Windows 10 Compressed Memory. In the first post Volatility and Rekall Tools, the FLARE team introduced updates to both memory forensic toolkits. These updates enabled these open source tools to analyze previously inaccessible...

kernel: kvm: guest userspace to guest kernel write

A flaw was found in the way Linux kernel KVM hypervisor emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check current privilegeCPL level while emulating unprivileged instructions. An unprivileged guest user/process could use this flaw to potentially escalate privileges inside...
